6 Claims. (Cl. 160-91) This invention relates to metal window and sash frames and more particularly to windows of the type having laterally slidable sashes.

The principal object of the invention is to provide a window designed to meet all weather conditions, particularly in regions in which dust storms prevail, the window being equipped with double glazing, adequately sealed against moisture and especially against dust infiltration, the double glazing, combined with the hollow extruded frame construction being effective to obviate excess moisture condensation.

Another object of the invention is to provide a sliding sash type window in which is mounted a stationary double glazed sash frame and a stationary screen frame in horizontal parallelism and a sliding double glazed sash frame which is roller mounted and is removable for cleaning and other purposes by sliding the sash frame to one side of the main frame, lifting its lower end and shifting the same toward the inside to displace the frame from its channels.

Still another object of the invention is to provide a is removable and replaceable without the necessity of detaching any part of the window.

Other objects will appear as the description proceeds when considered with the annexed drawings, wherein:

Figure 1 is a perspective view of the window as viewed from the inside of a building.

Figure 2 is a fragmentary view, partly in vertical section, showing the sash lock.

Figure 3 is a vertical sectional view taken on line 3--3- of Figure 1.

Figure 4 is a vertical sectional view taken on line 44 of Figure 1, and

Figure 5 is a transverse sectional view taken on line 5-5 of Figure 1 Continuing with a more detailed description of the drawing, reference is primarily made to Figure 1 wherein numeral denotes generally the complete window which is made up of a sill 11, parallel jambs 12 and a head member 13. The jams and head member are identical in transverse section, each being formed by extrusion. The jambs each are formed with an outer facing 14 having an anchoring flange 15 which is secured to the building fabrication by any suitable means but is shown in Figure 5 as being secured to wood fabrication 16 by screws 17. The opposite or inner edge of the jamb is provided with a flange 18 against which bears the interior wall finish 19. The flanges 15 and 18 are parallel with confronting faces, the flange 15 being provided with a lip 19 while the flange 18 has a lip or inturned edge 20 and extending between these flanges within the confines of the opposed lips 19 and 20 is a sill block 21. Each sill block 21 consists of a metal plate of a length to conform to the distance between the flanges 15 and 18 at the base of the jamb 12, as revealed in Figure 1, and whose lower edge is shaped to the profile of the top of the sill 11. Vertical slots 22 are formed in the outer surface of the sill block to receive screws 23 driven upwardly through the sill into the slots 22 to save the cost of drilling and tapping the blocks. Another screw is inserted into an aperture 24 in the sill block and is threaded into the jamb 12.

Figure 5 shows a complete transverse section through the window but also shows, at the right of the figure, the

manner in which two or more windows are joined together through the medium of a mullion 25 which lies between the jambs 12 of each window. The mullion 25 has an exposed portion or facing 26 exteriorly of the windows whose edges bear against the outer edges of the jamb facing 14 of the adjacent jambs 12. Vertical flanges 27 formed on the inner surface of the facing 26 provide reinforcing for the facing as well as affording a spacing means for the adjacent jambs 12. Vertical flanges 28 on the mullion 25 adjacent the facing 26 and similar flanges 29 adajacent the inner but narrower facing 30 of the mullion bear against the inturned ends of the flanges 18 of the jambs to prohibit lateral displacement of the mullion.

Referring again to the jamb structure; a vertical flange 31 is formed on the inner surface thereof and set inwardly from the flange 18 thereof and constitutes a finish flange whose upper end is mortised to an identical flange 32 formed on the undersurface of the head member 13, it being recalled that the cross-sectional shape of the head member and jambs is identical.

Opposite the vertical flange 31 of each jamb 12 is a vertical web 33 which is formed with a longitudinally coextensive undercut channel 34 which receives a weatherstrip 35 of conventional manufacture, the same consisting of a length of wire mesh 36 (Figure 5) to which is attached animal fibers 37 and along each edge of the wire mesh is a wire 38, the wires being adapted to lie in the undercut edges of the Weatherstrip channels 34 after the wire mesh has been collapsed and returned to its normal shape after insertion into the Weatherstrip channel 34. This construction enables a worn Weatherstrip to be pulled out of its channel and replaced by a new one without disturbing any other part of the window.

The vertical web 33 of each jamb 12 is integral at its inner edge with a right angular web 39 (Figure 5) which is formed with a vertical channeled portion 40 and a parallel channeled portion 41. A vertical meeting rail 42 extends from the sill 11 to the head member 13 midway between the jambs 12 and, as shown in Figure 5, is formed with a transverse web 43 in which is formed parallel channels 44 and 45 which are in confronting relationship with channels 41 and 40, respectively, of the web 39. The web 43 has a coextensive outer flange 46 which confronts the extended edge 47 of the outer facing 14 of the jamb 12. Disposed against the inner surfaces of the flange 46 and the extended edge 47 are the side edges of a pane of glass 48. A sash retaining strip 49 extends along the sides, top and bottom of the pane 48 and is provided with a longitudinal recess 50 in which is disposed a tubular rubber or neoprene sealing strip 51 which bears firmly against the inner surface of the pane 48. The sash retaining strip 49 has an extension 52 coextensive with its outer edge which lies in the channel 41 of the web 39 and bearing against the side of the retaining strip 49 opposite the pane 48 is a neoprene or rubber sealing strip 53, disposed in a longitudinal slot or recess 54 in a sash frame 55 in which is mounted a glass pane 56. A sash locking strip 57 has one edge disposed in the channel 40 and its outer edge bearing against the sash frame 55. Four of these sash locking strips are employed to hold the glass 56 in place, one at the top and the bottom and one at each side. These strips are removable by inserting a suitable instrument in holes 58 (Figure 1) and withdrawing from their respective channels and when removed, the sash frame 55, retaining strips 49 and pane 48 may be removed from the inside of the window.

Inasmuch as the sash retaining strips 49, sash frame 55 and sash locking strips 57 are the same about the entire perimeter of the glass panes 48 and 56, the same reference numerals have been used to identify like parts throughout as applied to these elements.

Adjacent the double sash assembly just described is a wire mesh screen 59 mounted in a frame 60. The screen frame 60 has a recessed flange 61 about its inner surface into which the edges of the screen are thrust and held therein by means of a rubber or plastic retainer 62. The outer surface of one side of the screen frame 61 bears against the extended edge 47 of the jamb facing 14 which confronts the extended edge holding the stationary sash while the opposite edge of the frame bears against the extended edge 63 of the meeting rail 42.

The meeting rail 42 is formed with a transverse web 64 opposite its web 43 which is shaped to define a channel 65. This channel confronts a like channel 66 formed in the transverse web 67 corresponding to the web 39 of the opposite jamb. The screen frame 61 is locked from the inside by means of pivoted cleats 68, secured to the sides of the frame by means of screws 69 and rotatable to endgajge in the channels 65 and 66, as shown in Figures 1 an The lower ends of the dual sashes 48 and 56 are retained by a horizontal support 70 (Figure 3) whose ends are brought up flush against the jambs 12 on each side. This support is formed with a horizontal web 71 shaped to define a channel 72 to receive the extension 52 of the sash retaining rail 49 and a parallel channel 73 for receiving the sash locking strip 57. The panel 73a extends from one jamb 12 to the other and an extension 74 along its upper edge provides a bearing for the lower edge of the glass pane 48 in the same manner that the extension 75 on the facing 14 of the head member 13 and the extensions 47, 46 and 53 of the jambs 12 and meeting rail 42, serve to support the top and side edges of the pane 48.

A depending flange 76 formed integral with the horizontal web 71 bears flush against a vertical portion '77 of the sill 11 and is secured thereto by screws 78. The panel or skirt 73a of the support 70 extends down and engages the inclined portion 79 of the sill 11 and conceals the screws 78.

At the opposite end of the sill 11 the screen frame 60 is supported on an inwardly turned flange 80 on the panel 73a and is secured thereto by screws 81 (Figure 4) extending upwardly through the flange 80 into the bottom of the screen frame 60,

Mounted for horizontal sliding displacement in the sash channel 82 (Figure 4) of the frame is a dual pane sash frame 83. This sash frame is composed of a horizontal top member 84, a horizontal bottom member 85 and a pair of vertical side members 86 (Figure The vertical side members 86 are secured to the top and bottom members 84 and 85 by means of bolts 87 (Figure 5), only the bottom bolts being visible in the drawing.

The sliding sash frame is supported by means of a pair of fiber rollers 88, mounted on shafts 89 whose ends are journaled in the sides of the bottom member 85 of the sash frame 83. The rollers engage a longitudinal rail 90, formed as an integral part of the horizontal portion 91 of the sill 11. The upper end or top member 84 of the sash 83 extends above the lower edge of the extension or depending flange 32 of the head member 13 and, when the frame 83 is shifted to a position to the left in Figure 1, it may be lifted until the lower edge of the bottom member 85 clears the rail 90 and moved outwardly and thus removed from its channel 82 for cleaning, replacement of weatherstrips 35 or for any other reason. However, when the sash frame 83 is moved to the right, as viewed in Figure 1, it cannot be removed for the reason that the downwardly projecting protuberance 92 (Figure 3), affixed to the underside of the head member 13 prevents upward displacement of the sash frame in this position. The protuberance 92 may be in the form of a rail or spaced apart rollers, as desired. The projection or protuberance is located at the side of the main frame occupied by the screen 59 as a safety measure, to discourage unlawful entry by precluding removal of the sash frame from the outside after cutting the screen.

The sash frame 83 has a glass pane 93 whose side edges bear against confronting flanges 94 integral with the side members 86 of the frame. A sash retaining strip 95 has a longitudinally coextensive recess containing a sealing strip 96 which is in firm engagement with the inner surface of the glass. An extension 97 on the retaining strip 95 enters a channel 98 formed in each of the end members 86 of the sash frame 83. Parallel with the glass pane 93 is an inner pane 99 whose edges are in sealing engagement with a frame 100. This frame is held in the sash frame 83 by means of locking strips 101 slidably received in channels 102 formed in the side members 86 of the sash frame 83.

The arrangement just described for retaining the glass panels 93 and 99 is identical and interchangeable with the arrangement previously described for retaining the glass panels in the stationary frame.

Each side member 86 of the sash frame has an elongate 4 vertically disposed projection 103 which serves as an operating handle for shifting the sash frame from side to side. The handles are each offset inwardly of the edges of the frame so that said edges may pass behind the extensions 31 (Figure 5) of the jambs 12.

In Figure 2 is shown in detail a sash lock which consists of a cylinder 104 formed on a base 105 which is secured by screws 106 to one of the side members 86 of the sash frame 83. A cylindrical extension 106 depends from a cap 107 which has an annular groove 108 in its underside between its periphery and the depending extension 106 to receive the upper end of the cylinder 104. The cylinder 104 has an annular groove 109 adjacent its upper end to receive a set screw 110 which allows the cap to turn on the cylinder but prevents displacement of the cap. A handle 111 is made integral with the cap and by rotating the handle, the cap is turned to rotate the extension 106 which has a deflected end 112 engaging a like deflected end 113 of a cylindrical plunger 114. The plunger 114 is vertically reciprocable but held against rotation by a pin 115 extending through a slot 116 in the wall of the cylinder 104. The plunger 114 is held in raised position by a coil spring 117 whose upper end bears against a shoulder 118, formed by reducing the lower end of the plunger, and at its lower end against an internal flange 119 on the lower end of the cylinder 104.

When the handle 111 is rotated, the plunger 114 will be moved downwardly into a selected hole in the longitudinally spaced group of holes 120 in the sill 11, thus to lock the sash at any desired position.

In any position of the sash frame 83, it is adequately sealed against infiltration of dust or moisture first by the weatherstrips 35 which extend around the top and sides thereof and finally by the inverted U-shaped strip 121, shown in transverse section at the bottom of Figure 3 and which occupies the space 122 in the lower or bottom member 85 between the rollers 88. The Weatherstrip 121 straddles the rail 90 and slides thereon without friction. The strip 121 is constructed in substantially the same manner as the strips 35 and like these strips, is readily removable for replacement.

Manifestly, the construction as shown and described is capable of some modification and such modification as may be construed to fall within the scope and meaning of the appended claims is also considered to be within the spirit and intent of the invention.
